Google's key points of evidence

Google has put together a presentation to defend its use of Java code in Android, the central issue in Oracle's patent and copyright lawsuit against the search giant.

The case, which entered its third day on Friday, hinges on whether Google's mobile operating system infringes on copyright and patents related to Java, which Oracle took charge of after its acquisition of Sun. For example, the Dalvik virtual machine in Android uses Java APIs, which Google argues it is allowed to do. Oracle disputes this.

The slideshow handed to the San Francisco court as part of Google's opening statement comes in at 71 pages — 20 shorter than the document presented by Oracle. This selection highlights Google's arguments in its defence and begins with Google's key points in evidence.

Oracle's failed Java phone

Once it has established its bona fides, Google plans to go on the attack and note what it says are Oracle's failed attempts to build its own smartphone. This slide from an internal Oracle presentation in June 2009 refers to the company's 'Project Java Phone'.

Failed Java platform projects

Sun itself failed more than once to get a Java platform for smartphones off the ground, according to Google.
